Measurement scope

Which soil parameters does Agni measure?

Agni currently reports seven parameters: pH, electrical conductivity (EC), nitrogen (N), phosphorus (P), potassium (K), moisture and temperature. These readings are inputs to decision support; they do not by themselves describe every aspect of soil health.

A field guide to the readings

Seven parameters, seven different meanings

No arbitrary ‘ideal’ range is shown because useful interpretation depends on method, crop and local conditions.

pH

Acidity or alkalinity

Shapes how soil chemistry and nutrient availability are discussed.

Keep the original unit and method
EC

Electrical conductivity

Adds context about the soil solution; method and conditions matter.

Keep the original unit and method
Moisture

Water at a point in time

Needs location, depth and recent conditions to be useful.

Keep the original unit and method
Temperature

Soil temperature

A time- and location-specific environmental reading.

Nitrogen

N reading

Not the same thing as a universal fertilizer dose.

Phosphorus

P reading

Interpretation can depend on the measurement method.

A reading is an observationIt becomes useful when sample, time, method and decision are known.

Interpretation limits

A single reading is a snapshot. Sampling position, soil heterogeneity, recent irrigation, weather, crop stage and calibration conditions can affect interpretation. Laboratory testing and qualified agronomic review remain appropriate when decisions require formal or higher-confidence analysis.

The seven current readings

  • pH: an indicator of soil acidity or alkalinity.
  • Electrical conductivity (EC): an indicator related to soluble salts and ionic conductivity.
  • Nitrogen (N): one of the three primary macronutrient readings reported by Agni.
  • Phosphorus (P): one of the three primary macronutrient readings reported by Agni.
  • Potassium (K): one of the three primary macronutrient readings reported by Agni.
  • Moisture: the soil-water reading at the time of measurement.
  • Temperature: the soil-temperature reading at the time of measurement.
